If Charles passes a physical and the Broncos’ medical staff gives a favorable prognosis, the expectation is for the Broncos and Charles to try to close out a contract for the veteran running back.

Charles, 30, who tore his right anterior cruciate ligament in October 2015, played in just three games last season because of pain in his knees. He had just 12 rushing attempts for the season before the Chiefs put him on injured reserve in November.

He had arthroscopic surgery on both knees, which prompted the move to injured reserve. The Chiefs could have activated Charles and moved him to the active roster for their final regular-season game, but they chose not to.

They then released him after season’s end. Charles also tore his left ACL in 2011, so the Broncos’ medical staff will likely be a big voice in the decision. But the Broncos are poised to try to sign Charles, as a situational player, if they get a favorable medical report.

Broncos executive vice president of football operations/general manager John Elway and coach Vance Joseph have made no secret they are looking for more potential big-play pop at running back. Their projected No. 1 back at the moment — C.J. Anderson — is coming off knee surgery, while Devontae Booker had a productive rookie season.
